Stem cell bioprocessing describes the main large-scale bioprocessing strategies for both stem cell culture and purification, envisaging the application of these cells for regenerative medicine and drug screening. Bioreactor configurations are described, including their applications for stem cell expansion, and stem cell separation techniques such as isolation and purification are discussed. Basic definitions are provided concerning the different types of stem cells, from adult stem cells to the more recent induced pluripotent stem cells. The main characteristics of these different stem cell types are described, alongside the molecular mechanisms underlying their self-renewal and differentiation. The book also focuses on methodologies currently used for in vitro stem cell culture under static conditions, including the challenge of xeno-free culture conditions, as well as culture parameters that influence stem cell culture. Approaches for both stem cell culture and separation in micro-scale conditions are presented, including the use of cellular microarrays for high-throughput screening of the effect of both soluble and extracellular matrix molecules. A further section is dedicated to application of stem cells for regenerative medicine. - Maintains a unique focus on both the basic stem cell biology concepts, and their translation to large-scale bioprocessing approaches - Envisages the use of stem cells in regenerative medicine and drug screening applications - Discusses the application of microscale techniques as a tool to perform basic stem cell biology studies

The discovery of uniform latex particles by polymer chemists of the Dow Chemical Company nearly 50 years ago opened up new exciting fields for scientists and physicians and established many new biomedical applications. Many in vitro diagnostic tests such as the latex agglutination tests, analytical cell and phagocytosis tests have since become rou tine. They were all developed on the basis of small particles bound to biological active molecules and fluorescent and radioactive markers. Further developments are ongoing, with the focus now shifted to applications of polymer particles in the controlled and di rected transport of drugs in living systems. Four important factors make microspheres interesting for in vivo applications: First, biocompatible polymer particles can be used to transport known amounts of drug and re lease them in a controlled fashion. Second, particles can be made of materials which bio degrade in living organisms without doing any harm. Third, particles with modified surfaces are able to avoid rapid capture by the reticuloendothelial system and therefore en hance their blood circulation time. Fourth, combining particles with specific molecules may allow organ-directed targeting.
